Description
To connect three-phase AC input power to the
control circuit.
For 460 V unit: 380 to 460 VAC +10%, -15%,
50/60 Hz +/-5%
To connect precharge/discharge resistor.
When the built-in resistor is used:
Jumper between PR2 and PR3, and open
PR1.
When an external resistor is used:
Connect the resistor between PR1 and
PR2, and open PR3.
When the unit is connected for power
regeneration mode only:
Open all the terminals PR1, PR2 and
PR3.
To supply AC power to the fan for the AC reactor
unit through the EM4000 EMC filter unit.
To enter fault signal of the fan for the AC reactor
unit.
To supply power to the main magnetic contactor
and the fan for the cabinet fan through the
8720MC-EF190 EMC filter unit.
To be used as the control terminals for the main
magnetic contactor.
